The Cornerstone project is aiming to transform Ebenezer Chapel, a disused chapel in the centre of Cardiff, into a centre for business conferences and events as well as social and community events. The project is being undertaken with financial assistance from the Heritage Lottery Fund and other charitable bodies.

The Grade II-listed former chapel in Charles Street was built in 1855. It is located opposite Cardiff Metropolitan Cathedral of St David and was purchased by the Catholic Archdiocese of Cardiff in May 2012.

Cornerstone is scheduled to open in autumn 2016.
